This invention relates to film magazines and particularly to lmmagazines adapted to contain film for amateur cameras. One object of myinvention is to provide a magazine which is 5 simple to construct andeconomical to build. Another object of my invention is to provide amagazine with a locating plate adapted to position the magazine in asuitablecamera. Another object of my invention is to provide a lmmagazine with totally separate containers for the unexposed and for theexposed lm. Another object of my invention is to provide a magazine withlm containers attached to a plate having edges shaped to cooperate withwalls of a camera 5 to position the magazine therein. Still anotherobject of my invention is to provide a lm magazine comprising lmcontainers mounted on a plate two edges of which form runners adapted toengage a track in a camera to position the 0 lm magazine and otherobjects will appear from the following specification, the novel featuresbeing particularly pointed out in the claims at the end thereof.

Coming now to the drawing in which like characters denote like partsthroughout:

Fig. 1 is a plan view of a magazine constructed in accordance with andembodying a preferred form of my invention;

Fig. 2 is a plan view of the blank from which a m part of the magazineis formed;

Fig.'3 is a plan view of one section of a lm container;

Fig. 4 is an enlarged fragmentary view showing a port-ion of alight-tight channel leading to l5 a film container;

Fig. 5 is an end viewof the light-tight` channel for the lm containers;

Fig. 6 is a view of the blank from which the light-tight channel for thenlm containers is i0 folded;

Fig. 7 is a side elevation of a second section of a film container; and

Fig. 8 is a section through the magazine shown in Fig. 1 taken on line1'-1 thereof with parts i5 of a camera diagrammatically shown.

A preferred form of my film magazine cornprises a base plate which mayconsist of a thin sheet metal plate I havingperforations 2 and 3 for thenlm winding and supporting mecha- 50 nism to be hereinafter more fullydescribed and having perforations I through which ligs i of the outersection O of the film container may pass so as to attach the filmcontainers permanently in place by bending the'lugs I dat against the 55bottomloftheplateasbestshowninrig.

The plate I may be made of comparatively thin sheet metal and if it isnecessary to strengthen this plate a flange 8 may be provided, which, asindicated in Fig. 2, may be bent upwardly along the line 8 to reinforcethe plate I. However, this flange is not necessary.

'Ihe film containers are similar in shape and consist in two parts. Aninner part I0 is shown in Fig. 3 as consisting of a disc II which mayhavel formed up members I2 in the bottom to 10 reinforce the metal andto facilitate positioning a coilof film. From the periphery of thebottom II a flange I3 extends upwardlyfthis flange being provided with apair of spaced, outwardly bent ends Il and I5 forming tracks on which 15cooperating anges `I6 and I1 of the light-tight channel I8 may slide.'This channel is made light-tight by means of plush or other pile fabricI9 which is preferably dark in color or black. As indicated in Fig. 3 asmall section 20 of the 20 fabric is placed on the lower wall lIl of themagazine.

In order to hold section III of the lm container in place a secondsection 6 is provided as shown in Fig. 1, this section consisting of an25 upper wall 2I from which there is a downwardly extending ange 22 ofsuch size that it telescopes flange I3 of section Il. This member has acutaway portion 23 in one side to permit the lighttight channel Il to exd to section I0 and the 30 flange 22 is preferab provided with a pair oflugs 5, these lugs being adapted to enter the slots 4 and to be foldedover against the bottom 1- of plate I to hold the nlm magazine in place.

As indicated in Fig. 1 the film containers des- 35 ignated broadly as Cand C1 are similar in structure except as to the location of thelight-tight channels Il. Two of these are mounted on Ieach plate I andit should be noted that the edges of the plete extend out' beyond -theedges 40 of the cylindrical lm containers.

The reason for this construction is that the plate I is provided with atleast two edges 24 `and 2i which in the preferred form shown areparallel to eeen other and are adapted to exigage walls of a.' camera toposition the magazine therein.

For instance, a preferred vform of locatingmeansisshowninllig.8whereintheedge24 5oand!!areadaptedtoslideinthegroovesllY `and 21, thus iixedly holding themagazine in a desired position in a camera.

It is..of course,vpossible to locate the plate I mamenbytnenuszczaumauu36 may be the camera may have an opening adapted to receive such aplate.

In both cases my magazine has the advantage that it may be easilyplaced, into and taken out of a camera. The reason for this is asfollows: Normally both walls of a magazine are of substantially the samesize and shape and where this is true and the magazine ts closely into acamera, it is diflicult to get a hold of the magazine to remove it.

However, it will be noticed that with a magazine as shown in theaccompanying drawing one 'side of the magazine in effect consists of afiat 'plate I which is considerably larger than the other side of themagazine which consists of the top walls of the lm containers .C and C1thus even if the plate I does t accurately into an opening there is leftplentyof room in the outer wall of the .magazine that is, the outerwalls of C and C1 by which an operator may grasp one of the lmcontainers or both to readily remove the magazine Vfrom the camera.

` In Fig. 6 I have shown a blank of metal from which a light-tightchannel I8 may be folded up. This consists of a pair of dissimilar walls30 and 3| connected by a narrow wall 32. Walls '30 and 3| are bent alongthe lines 33 and 34 into substantially parallel relation. Flaps 35 andbent along the lines 3'I and 38 to hold the plush or material I9 at oneend. The flanges I6 and Il which engage the cooperating flanges I4 andI5 on the lm containers are folded from the ends of parts 30 and 3| byfolding the metal in a plurality of folds along the lines shown at 39and 40.

As indicated in Fig. 8 each spool container is provided with a. hub forthe. film. Normally spool container C is for the supply of unexposedfilm and this may be wound upon a hub member 4| adapted to turn freelyupon the upturned ange 42 of section I0 of the spool container. This hubdoes not necessarily have power applied to it and may turn freely afterthe film F is moved by the camera mechanism.

Spool container C1 is normally to receive the exposed film and may bepower driven by means of a shaft 43, this shaft extending into theaperture 44 and'having a driving engagement therewith through a clutchmember 43 and 44' so as to turn the spool hub 45 to which the film maybe axed by a metal sleeve 46. As the mounting of the supply and take-upreel in this magalzine forms no part of my invention, it will not Havingthus described my invention, what 1 claim as new and desire to secure byLetters Patent is: n
